Magnesium is one of the most important — and most overlooked — minerals in your body. It supports sleep, stress management, muscle function, energy levels, and even heart health.

And yet, it’s estimated that 7 out of 10 people don’t get enough magnesium from diet alone. This guide will help you understand what magnesium does, how to know if you’re low, and how to choose the best magnesium supplement in the UK.

✅ The Best Forms of Magnesium (What to Look For)

Not all magnesium supplements are the same — and some are far better absorbed than others.

Here are the best forms:

• Magnesium Glycinate – Highly absorbable and gentle on the stomach. Great for anxiety and sleep.
• Magnesium Citrate – Good absorption, can help with digestion and constipation.
• Magnesium Malate – Supports energy and muscle performance.
• Magnesium Threonate – Targets the brain, supports cognitive function (more expensive).
• Avoid: Magnesium oxide – cheap and poorly absorbed.

💊 How to Take Magnesium

• When: Take in the evening for better sleep, or after meals to improve absorption.
• With food: Helps reduce the chance of loose stools.
• Start low: Especially with magnesium citrate, which can have a laxative effect if taken in high doses.

The recommended daily dose is around 300–400mg for most adults.
